You buy something, then buy something else, then buy something else, and so on, and so on, until you just can buy anything else. Then you leave and go somewhere else to loiter.

Don't loiter; it's really that simple.
You can certainly buy something like a coffee or tea and drink it outside; that will probably work just fine. But, hanging around and doing nothing, though not necessarily wrong, is not good optics.

it depends on what country you are in really but...

the reason you were kicked off by the security guard was because he thought you were up to no good. i dont know how oldd you are but if you are young, it's advisable to look as respectable and well-meaning as possible. look busy but not suspiscious; read a book, text some friends, eat some food or drink. dont attract attention in any way. if you are older, then it's likely that you can reason with the guard by talking to them in a calm civilised manner, and explain that you are doing no harm, and are simply relaxing.

If you purchase something, you probably won't be asked to leave because you're not loitering at that point; you're a paying customer. I think that's a good idea; buy something from the store and sit outside to enjoy it.
